Abstract
A dopant composition for organic semiconductors is an electron acceptor characterized by an evaporation point above 150° C. or a glass phase. The dopant composition includes a compound represented by structural formula (1): wherein R1 to R5 are independently hydrogen, chlorine, fluorine, nitro, or cyano; or a phenyl or annulated aromatic group optionally substituted with chlorine or fluorine. Also included are doped organic semiconductors and organic electronic components comprising the dopant composition, and methods of preparing the doped organic semiconductor.
